T0 a ll whom it may concern Be it-knownthat I, ISAAC PHILLIPS, of Bure lington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Smut-Machines for Cleansing Grain; and 'rl'do-hereby declare that the following is. a full, clear, and exact description thereof, reference being had to the accompanying drawings and the letters and figures marked thereon, which form part of this specification.

In the said drawings, which are'hereunto annexed, Figure 1 represents a vertical section of my invention through the center thereof; Fig. 2, a horizontal section at the line a: in Fig. 1; vFig. 3, a similar view at the line 3 in Fig. 1, and Fig.4 a perspective view-of one of my improved heaters for cleaning th grain.- v I Theobject of-my invention-- is to o tain-asmut-machine for cleansing and purifying wheat and other grain, and removing and separating therefrom all impurities of whatever kind, preparatory to grinding said grain into flour,.wh ich shall be simple and cheap in l i construction, and at the same time ett'ect the purpose of such a machinein a much more perfect manner than has hitherto been done. I

it also consists in so constructing said machine that itwill perform its work equally "well, whether the vertical shaft propelling saidshaken by means of a small crank upon the upper end of the shaft B, towhich it is attached, and which is revolved by means of a.

1 belt passing around the drum B and the power-shaft propelling the machine.

0 represents a vertical perforated and corrugated cylinder, of sheet-iron or other suita ble metal, within which the apparatus for cleaning'the grain is situated, which apparatus consists in the following-described parts and devices-z E and F represent ,two'devices for beatingthe grain, being made of cast-iron orany other suitable metal, whose construction is clearly shown in. Fig. 4. The said cylinder has a closed top,-at the center whereof there is abearing for the-upper end of the vertical shaft D, whose lower end rests in a suitable bearing in the lower frame of the machine, as shown in the drawings. The said'cylinder-has also an opening through the top to admit the grain within it, which openingis surrounded by a close passage (marked P in thedra-wings) ex-r tending upward and opening into the box G. The interior surface .ofthe top of the cylinder is corrugated, as shown, as also is the upper surface of the heaters E and. F, which-are fixedupon the revolving shaft 1) and revolve with it, said shaft. being driven by means of a belt passing "around the'drum D, in the same manner as the shaft 13 is driven. About half-way down the cylinder it is provided with an annular ledge; projecting inward,

(marked 0,)whose lower surface isalso corrugated; and fixed upon the shaft D, just above said annular ledge c, is the bar a, provided with forked ends, as clearly shown in Fig. '3,

and just below said annular ledge c is thebeater'F, constructed and operating in thesame manner as E.

b represents a spout or chute whereby the grain, after passing through the heaters, passes out from the cylinder'O. v

Arranged upon the shaft D, below the above-described beatingdevice, is a revolving fan, J, inclosed in a tight circular box, for the purpose of inducing currents of air to pass through the grain and take out and carry off the impurities detached and separated therefrom by the above-described apparatus.

H, I I, and l are pipes or flues through which the currents of air induced .by-the operation of the fanJ pass. The'flues I I open, respectively,into two horizontal passages arranged on each side of the fan-box, which lead out over the smut-box K, into which they open downwardly.

L and M represent two openings from the fan-box to provide for the escape. of air therefrom when the fan is in motion, and by closin g either one and leaving the other open the 1achments,.to be revolving. falls upon theshaking screen A, it, passes fan may be revolved either '-waywith ei ual facility and effect. It will be observedvu-lso from the configuration of the perimeter of the when that side of the hearings or journalbox becomes worn, so as to render tlhe belt. loose upon the drums and liable to slip down, the

- difficulty may be obviated byrnoving the adjustable bearing 11 around sonsto present. an unworn part'to the frictional action of the shaft. i 3

Having thus described. and'ishown the con-'- struction of my improved smut-machin e', Iiwill nowproceed to describe the operation thereof, supposing the shafts B and D, with their at As the grain through the upper screen, a, andffallsupon' the sloping board I), which carries itvback to the end ofv the screen, where .it falls upon the screen 0, through which it passes, aiid goes out from the screen through the spouts into the scouring apparatus, the heaters E and F and the forked arm a in themeanwhile revolving rapidly. 'lhegrain fallingupon the upper surface of E is secured between-it and the corrugated surface, above, and, passing down, the projecting sides oif E and thecorru gated interior surface of -thejiuclosingcylinder again scour the grain, which falls upon t-heledge 0,

whence, by the revolving arm a, it is gathered and thrown upon the beater F, by. which the same process is repeated, and the grain falls to the-bottomof the cylinder and passes-out tlrough the chute b, perfectly clcanand pure.

In the meantime the operation of the fan J,

forcing the air out at theoutlet M, induces a current ofair or a'draft in 'the direction of the black arrows up through the flue H and through perforations in P, just beneath the spout .9, through which the grain passes from the screen into'the scouringapparatus, as shown, and also through the spout b and the apparatus in E and Fund the perforations in the cylinder 0, all said currents passing up through the falliug'grain, whose course isindicatedv by the-red arrows, into the chamber G, separating'jand bearin g the filth and smut away from the grain -and thence passing down through the flues-I landthe horizontal passagesaioresaid, into which said last-memtioned'fluesopen, depositing thesmut in the chamber. K, and passing in the direction of the said black jarrows into the fan-box, to be driven out through the outlet M by'the nevolution of the fan, as aforesaid. By closing the outlet M and opening the valve atL, and revolving the fan in the reversedirection, the

air is forced out at L with exactly the same result, and by thepeculiar arrangement of the parts within the cylinder 0 the reverse motion of'the shaitwill produce exactly thesam .efi'ect'upou the grain, 1

Having thus described the construction and operationl ofinyinvention, I will now specify what I claimas new and desire tosecure by LettersPatent:

1. Rroviding the cylinder C with one or more ledges, c, in combination with the beat ers E antlF-and thearm a, arranged and operating substantially its-herein set forth and 2. Providing the heaters E and F with the rel-entrant faces m 1i,'when used in combination with the ledges c andthe pron ged arm a,

as and for the purposes herein specified and shown.
